yes, at one point my Dodge(Chrysler) Neon had a Motorcraft (US brand for Ford Genuine parts, FoMoCo) Filter and Motorcraft Oil in it. it was fine.in fact Motorcraft filters are pretty popular with Jeep guys, for the old AMC 4.0l inline 6.(Jeep now owned by Chrysler, who in turn is now owned by Fiat)

A few years ago, many BITOGERS bought Ford Motorcraft oil on sale, and used it everywhere. Currently, many people are using "TGMO" meaning "Toyota Genuine Motor Oil" and use it in cars not made by Toyota.

Another thing to keep in mind is than many OEM oils were actually made by some major oil company, and then given a new label. Ford Motorcraft was made by ConocoPhillips, and many Toyota oils have bottles that are eerily similar to Exxon Superflo.
